 Imaging: A brighter future for cell tracking  | Fluorescent organic nanoparticles operating as cell tracers outperform existing methods for long-term tracking of living cells. | Read More » Data storage: Better hard drives ready for lift-off  | Operating a hard disk drive is as complex as keeping a superfast car on the road. Read/write heads within the hard disk must process a huge amount of data at high speed. Controlling the motion of the slider housing these heads is crucial: if the slider crashes, it could destroy the hard disk. | Read More » Data storage: Maintaining privacy on the cloud  | A data-sharing scheme utilizing an encryption manager shows the way towards low-cost, flexible and secure cloud storage services. | Read More » Optics: Nanotechnology's benefits brought into focus  | Conventional lenses, made of shaped glass, are limited in how precisely they can redirect beams of incoming light and make them meet at a point. Now, scientists have proposed a novel approach to 'superlens' systems that can surpass this classical limit of focusing light. | Read More » Microelectronics: Automating cancer detection  | Microelectronic engineers have developed and tested sensor technology that can detect and measure a chemical signature of bladder cancer. The light-based sensor could eventually be used for the early diagnosis and subsequent tracking of the progression and treatment of many different tumors, according to researchers. | Read More » Solar energy: A richer harvest on the horizon  | Theoretical simulations reveal that layered semiconductors with magnetic interfaces are potent catalysts for solar energy capture and conversion. | Read More » Nanoparticles: Polymer knots with silicon hearts  | Biocompatible complexes for drug delivery applications get a structural boost from nanoscale silicon cages. | Read More » |
